I just spoke with Mass General. Talking again next week to someone else. Today I was assessed for eligibility for their pre-clinical stem cell trial. I am not eligible bc my PD is not advanced enough. They are looking for 10 PWP as soon as possible. Phase 1 clinical to follow in a couple years. Those who participate in the pre-clinical will have the greatest chance of being in the next phase. This was already done through every phase in a retired doctor named George Lopez. Follow the link and on the right side there is a button to email them. State your interest and that you are able to come to the hospital once a year for a couple years and that you are responsive to Levodopa.
